Something like that, yes. It's not a big problem that it's old. The
problem is that we have too many compilers in main which is a
maintenance nightmare.

That's *almost* what qemu is anyway :)

VirtualBox, like kvm, uses qemu's device model, and nothing else, AFAIK,
and it's only the cpu emulation stuff that requires the older gcc, so
